ira_set_viewport · IRA-RESEARCHER MCP: Risk & Policy

WHAT IT DOES

What ira_set_viewport does on IRA-RESEARCHER

AI agents invoke ira_set_viewport to trigger actions in IRA-RESEARCHER. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why ira_set_viewport needs a policy

Setting the viewport modifies the browser's rendering environment, which is an external operation affecting how subsequent actions behave. It's not purely reading data, but it's also a low-risk configuration change with minimal blast radius. It falls under Execute as it triggers a browser-side operation.

From the tool's definition 'Set browser viewport size' — triggers a browser configuration action that changes the active browser state
